Field stories: heat wave

After the windy June, we had really been waiting for sunny days with no wind. But never would I ever had imagine that I would shout out of joy on last Tuesday morning when the wind was 6 m/s!

We have been experiencing a heat wave in the Bothnian Bay this week. On Monday we moved to the Bothnian Bay National Park and it was 27 degrees Celsius at the sea! We were so happy about the warmth, the sun and the calm sea. But we were not as happy when we had to put on the survival suit, or the dry suit for diving. Or when we had to go to sleep in the cabin with has extremely hot after the hot day. So on Tuesday morning when the wind was a bit stronger for a couple of hours in the morning, we all enjoyed the boat ride to the mapping points in the tiny islands of the National Park.

The days have been quite rough with the heat wave and the not being able to sleep in the hot cabin. But because the sea has been so calm, we have already almost finished all the work that I had planned for us for the next two weeks! So next week we can do some extra mapping and focus on getting the data to Excels 🙂

With this weather is good to avoid exercising too much, so we towed the SUPs from one island to another, and took videos with MAIA-boat while the girls were doing wading points with SUPs (Photo by Teemu Uutela, Metsähallitus).

Hopefully the sunny days continue, but our team would not mind if the temperatures would drop under 25 degrees.. 😉

Ps. On today’s morning dive it was 20 degrees Celsius on a depth of 4 meters, it really is Summer now!
